The MPC-CC provides a monthly status of the quality of Sentinel-2 products via a Data Quality Report (DQR). The DQR provides information on the monitoring and measurement of product performances against the proposed specification, viz:

Geometric Performance

Geometric Calibration Status

Absolute Geolocation

Multi-Spectral Registration

Multi-Temporal Registration

Radiometric Performance

Radiometric Calibration Status

Radiometric Uncertainty

Noise

Modulation Transfer Function

It also documents observed anomalies and known issues, the list of defective pixels, and any processing chain improvements resulting in an increment of the Processing Baseline.
